I don't know... When it comes to a husband, I'm reluctant to bombard him or be too overtly-stubborn. I think that if you attack him too much with information, that he'll just not want to listen anymore. Do you want him to just give in or to actually support you? Maybe it's time to think really hard about your emotions regarding this and let him know, either in a long talk or maybe in a letter. I'm not saying give in to the pressure to go outside of the home at all, I'm just saying that taking a more understanding approach will probably be more effective in swaying him. Say, "I've done a lot of reading and I really fell like this is the safest thing for me and for our baby." (not that you haven't said that, just giving suggestions). Try: "I really feel like you're not listening to me, to what I'm trying to show you. I feel like my feelings about this very intense and inherently important event are not being considered by you." "I really want you to be a part of this birth, to be a part of the decision making, that's important to me, but protecting myself and our baby is more important. I want to include you, but I feel like you're not letting me. If you just try to read some of these materials, you can see what I'm talking about." Maybe put together a synopsis of some of the most important points from the books with citations so he can see some basic "talking points" and then may be more inclined to take a harder look. Try showing him this flash video of a homebirth:

Born in the USA. You can order it online, I imagine, or get it at the library (if they don't have it, request an Inter-library loan). Or perhaps a midwife or birth instructor in your area would have it. Just some ideas.
